What is one major hazard when handling a power supply?

The major hazard when handling a power supply focuses on the inherent dangers associated with electrical components. Power supplies convert AC (alternating current) from wall outlets into DC (direct current) used by computers and other devices. They contain high voltages and can store electrical energy even after being unplugged. Therefore, improper handling can pose significant risks of electric shock or injury. Awareness and caution are critical when dealing with these components to prevent accidents.

While overheating, harmful fumes, and data loss due to disconnections are important concerns, they do not encapsulate the immediate danger involved in handling power supplies as effectively as the awareness of its electrical nature and the precautions it necessitates. Hence, emphasizing the need for caution is paramount for safety when working with power supplies.
